  • Patent number: 11887091
    Abstract: Provided is a money handling apparatus that can be easily introduced in a store. The money handling system includes: a money handling apparatus installed in a store and capable of executing basic functions including a checkout function; and a operation terminal connected to the money handling apparatus. When executing the checkout function, the money handling apparatus receives, through the operation terminal, an input of prices and quantities of items a customer purchases in the store, to calculate a transaction amount. The apparatus recognizes and counts money, which is deposited through an inlet for paying the transaction amount, to calculate a deposit amount of deposited money, and stores the deposited money inside the money handling apparatus. When the deposit amount exceeds the transaction amount, the money handling apparatus feeds out money corresponding to a difference therebetween, and dispenses the fed out money as change to an outlet.

  • Patent number: 11007411
    Abstract: Provided is a method for manufacturing an iron golf club head by forging a single round rod member with a pair of dies to form, as a single piece, a body and a neck into which a shaft is to be inserted. The method includes: a first step of heating the single round rod member into a heated material; a second step of placing the heated material in the pair of dies; and a third step of forging the heated material placed in the pair of dies. In the third step, the heated material is prevented from flowing out from parting surfaces of the respective dies at a sole side of the body in the pair of dies, and the heated material blocked at the sole side in the pair of dies flows toward each of a toe of the body and the neck in the pair of dies.
